The code i'd used

/**
 * Filter an iterable using a filter function.
 * @param {Iterable.<T>} list
 * @param {function(T, number, T[]):boolean} filter
 * @template T
 * @returns {Array.<T>}
 */
const all = exports.all = (list, filter) => [...list].filter(filter)

Thanks. This looks like an issue with TypeScript which powers our JavaScript language support. I've opened microsoft/TypeScript#18085 to track this upstream

Closing as upstream
